Yes, I am in general agreement regarding using 8 PIC chips, one for each DCO. And hopefully, each can take a voltage control signal for envelope generator VCA control. Because we already have those available in the existing circuitry. Then we also need another voltage control input for frequency control. So that MG and joystick pitch bend can control each PIC oscillator. Finally, we also need detuning (which can be digital control.

Maybe the topic got buried in the other thread, but there was mention of trying to build a new voice for the HAWK.
I was suggesting perhaps we try to use a simple 8bit PIC with a small wavetable set, one PIC for each voice. So maybe a 6 or 8 chip voice board? Imagine the combo's you could come up with since each voice could be a different wavesample.
I put a line out to the guy who wrote the code for the Electric Druid's VC DCO pic chip. He might give some pointers on how to mod his wavetable PIC code to work with a digital uC instead of all VC.
I did post questions to Mike about some of the features he was after.. I think my post got covered over and lost before he saw it??
